STEAM-ELIMINATOR.

Specification of Letters Patent.

Patented Dec. 25, 1906.

To Ml whom it may concern:

Be it known that we, WILLIAM LLOYD, JOHN LLOYD, and SAMUEL T. NIOEOLsON,citizens of the United States of America, residing at Wilkes-Barre, inthe county of Luzerne, in the State of Pennsylvania, have inventedcertain new and useful Improvements in Steam-Eliminators, of which thefollowing is a specification.

Our invention relates to improvements in steam eliminators or separatorsfor the pur pose of eliminating water, entrained moisture, grease, oil,or other impurities from steam and automatically discharging sucheliminated water, &c., without waste or loss of steam.

Our present invention is primarily in the nature of an improvement uponthe steameliminators set forth in Patents No. 600,921, dated March 22,1898, and No. 677,458, dated July 2, 1901.

The main object of this invention is to so improve the construction andmode of operation of the apparatus as to make its action in opening andclosing more certain.

Other features of improvement will be disclosed in the followingdescription.

In the accompanying drawings, Figure 1 is a vertical section of myimproved construction of steam-eliminator. Fig. 1 is a crosssection ofthe main valve into the collectingchamber, showing a by-pass valve. Fig.2 is a sectional plan on the .line 2 2, Fig. 1, but drawn to a reducedscale. Fig. 3 is a side elevation of the trip apparatus, drawn to alarger scale than Fig. 1 and with some of the parts in differentpositions from those of Fig. 1. Fig. 4 is a view of this trip apparatusfrom the reverse side in a section taken on the line 4 4, Fig. 5. Fig. 5is a plan view of the trip apparatus, and Fig. 6 is a vertical sectionof a modification.

In Figs. 1 and 2, A is the baffle-chamber with steam-inlet B andsteam-outlet O. Below is the collecting-chamber D with an intermediatevalve E. In Patent No. 677,458 a gate-valve was described; but insteadof the gate-valve we use a seated valve carried by a vertical spindle e,threaded at e and passing through a stuffing-boxy in the top of thecasing and provided on the outside with a hand-wheel f, by turning whichthe valve E may be raised off or set down onto its seat F. Thisvalve-seat is attached to or forms part of a flange F, which is clampedbetween the flanges of the baflie-chamber and the collecting-chamber.

The construction of the baffles will be clearly seen from Fig. 2. Thebafiies include two corrugated plates 10, cast with or attached to theside walls of the baffle-chamber and set radially therein, and twotransverse plates 11 11, with corrugated faces, these transverse platesbeing also attached to or cast with the body of the baflie-chamber andstanding across the middle of the steam-passage through the casing.These corrugated baffle-plates 11 11 are provided with inner ribs 12,arranged radially of the vertical aXis of the bafiie-chamber.

We prefer to provide the collecting-chamber with a steam-actuatedoutlet-valve G, covered by a suitable perforated screen 13. Thiswater-discharge valve G is carried on and opened by the stem 14 of thepiston 15, which works in the short cylinder 16. This cylinder on oneside of the piston is open through the passage 17 to the water-outlet18. On the other side of the piston there is a connection through apassage 19 (indicated by dotted lines in Fig. 1) to a valve 20 in thesteam-space of the collecting-chamber, and this valve is controlled bythe floatandtrip mechanism to be described. A spring insures the closingof the valve G to its seat. In Patent No. 677,458 a slide-valve is shownto control a steam-passage, such as 19; but we have substituted for theslide-valve a seatvalve 20, as shown more clearly in Figs. 3 and 4. Thevalve 20 is carried by a lever 22, pivoted at 23 to the frame H, whichis bolted or otherwise secured to some suitable part of the casing ofthe collecting-chamber. The valve is normally pressed to its seat by aspiral spring 24, acting on a collar 25 on the lower end of a spindle26, which is pivoted at its upper end to the lever 22. The spring 24bears at its upper end against the under side of the frame H, Fig. 4.

To open the valve against the action of this spiral spring 24, weprovide a cross-shaft 27, mounted in bearings in the frame H andcarrying at one end a weighted lever 28 and at the other end a crank 29,with crank-pin 30 engaging the forked lower end of the upright spindle26.

On the outside of the fixed sleeve, through which the shaft 27 passes,Fig. 5, is pivoted the lever 31, which carries at its lower end thefloat 32. This float-lever has a pin-andslot connection with theweighted lever 28, as by a pin 33 on the float-lever working in a slot34 in the forward extension 35 of the weighted lever.

Pivoted to a suitable part of the frame H is a weighted catch-lever 36,the purpose of which is to engage with the shoulder 37 on the weightedlever 28 when the descent of the float has tilted this lever 28 to theposition shown in Figs. 1 and 3. The long arm of this catch-lever 36 isin such a position as to be acted on by a projecting piece, such as anantifrictionroller 38, on the float-lever when the float rises on a riseof water in the collecting-chamber.

In addition to the several parts named we provide a safety-catch 39,pivoted at 40 to the frame H and normally acted on by a spring 41, Fig.4, tending to throw the lever to the position shown in that figure. Thelower end of this lever 39 has a pin-and-slot connection with a link 42on a crank 43, secured to the shaft 27. A screw 44 permits of anadjustment of this ,pin-and-slot connection.

The operation of the described device is as follows: When the water inthe collectingchamber is at its lowest level, the parts will be in theposition shown in Fig. 1, with the ballfloat down and the weighted endof the lever 28 tipped up and held by the catch-lever 36 in the positionshown. The safety-catch lever 39 has also been drawn back at its lowestend by the crank 43 and out of engage ment at its upper end with thelever 22, carrying the valve 20, so that the latter is then firmly heldto its seat by the spring 24. As the water accumulates in thecollectingchamber the float will rise, and its antifriction-roller 38coming into contact with the catch-lever 36 will throw the latter out ofengagement with the shoulder 37 of the counterweighted lever. Theweighted end of the latter will then instantly fall to the positionshown in Fig. 4 and through its shaft 27 will lift the spindle 26 andlever 22 against the action of the spring 24 and raise the valve 20 fromits seat. At the same time the simultaneous movement of the crank 43 onthe shaft 27 will free the lower end of the lever 39, so that the spring41 will throw the upper end of the safety-catch lever 39 under the noseof the lever 22 to maintain the valve 20 in the open position untilsuflicient quantity of water has been allowed to flow from thecollecting-chamber to warrant the closing of the valve again. As thefloat descends its pin-and-slot connection with the lever 28 willelevate the weighted end of the latter and will lower its opposite enduntil the nose of the catch-lever 36 slips over the shoulder of thelever 28 and looks it in the position of Fig. l, as indicated in Fig. 3,and then immediately thereafter the lever 39 will have been pulled outfrom under the nose of the lever 22. We so adjust the parts that theaction will be that describedthat is to say, that the counterweightedlever 28 will be locked for a certainty before the valve 20 is allowedto close.

On the larger machines the main valve E, opening into thecollecting-chamber D, .is supplemented by a by-pass valve, asillustrated in Fig. 1 the purpose of which is to permit the equalizationof the steam-pressure in the baffle and collecting chambers, and thusease the raising of the main valve E. Lateral openings or a in the neckof the valve E admit the steam from the bafflechamber to the chamber X,and vertical openings b b in the valve-plate permit its passage into thecollecting-chamber D upon the raising of the spindle 6 before the valveE is raised from. its seat. When the spindle e is depressed again, thehead 0 will come to its seat and close the communication through thepassages a a and b I).

In Fig. 6 we have shown a modification in which the water-outlet valveinstead of being operated by the steam-pressure is operated by directmechanical connection from the lever 22. This is accomplished simply bypivoting to the lever 22 in place of the steamvalve a long stem 45,having at its lower end a valve 46, adapted to a seat 47 in a piece 49,screwed or otherwise attached to the casing. We may also make provisionfor operating this water-valve by hand. For this purpose we may secureto the stem 45 a collar 51, on the under side of which bears a bentlever 52, whose other arm is acted upon by a stem 53, passing through astufling-box in the casing, so that by inward movement of the stemactuated by a handle on the outside the valve 46 may be raised from itsseat by hand, if desired. In this casing, Fig. 6, we have shown adifferent form of inlet from the baifle-chamber from that illustrated inFig. 1. In Fig. 6 we have shown it as ada ted for a pipe connection,either to the bafflh-chamber or to any other source of water-supply.Immediately under the water-inlet 54 is a distributingplate 55, so thatthe full force of an inrush of water may not come directly onto thefloat.

We claim as our invention 1. The combination of a collecting-chamberhaving a water-discharge valve, with a weighted lever controlling saidvalve, a float cooperating with said lever, a safety-catch to hold thevalve open while the float is falling, a catch-lever to hold theweighted lever up until tripped by the float, and a connection from theweighted lever to the safety-catch to operate the latter.

2. The combination of a collecting-chamber having a water-dischargevalve with a spring actuated means tending to close the valve, aweighted lever to open it, a float controlling the lever, a safety-catchto hold the valve open while the float is falling and means to trip thesafety-catch when the float has descended.

3. The combination of a collecting-chamber having a water-dischargevalve with a weighted lever controlling said valve, a float cooperatingwith said lever, a safety-catch to hold the valve open while the floatis descending and means for tripping it, and a catch-lever to hold theweighted lever up until tripped by the float. i

4. The combination of a collecting-chamber having a water-dischargevalveand a piston controlling said valve, with a valve controlling the supplyof steam to the said piston, a spring and a weighted lever controllingsaid steam-valve, a float cooperating with the weighted lever, asafety-catch to hold the steam-valve open while the float is falling andmeans to trip the safety-catch when the float has descended.

5. A steam-eliminator having a bafllechamber containing baffle-platesand below that a collecting-chamber with a valve between the two havinga vertically-operating stem passing u between the baffle-plates andthrough a stu ng-boX in the top of the casing.

In testimony whereof we have signed our names to this specification inthe presenceof two subscribing witnesses.
